Amazed by the snowfall, Giant panda Sijia found herself a naughty baby cub again at the age of 13 years old.

SHANGZHI, Nov. 14, 2019 (Xinhua) -- A snowfall hit part of Heilongjiang on Wednesday, making the giant panda living here quite delighted. Giant panda Sijia was born at the China Conservation and Research Center for the Giant Panda in Wolong of southwest China's Sichuan Province on Aug. 12, 2006 and has been living in Yabuli since July 5, 2016.

Pandas were downgraded from "endangered" to "vulnerable" by the International Union for Conservation of Nature in September, 2016, thanks to continued efforts to protect the species by Chinese scientists. But the number of pandas living in the wild is still fewer than 2,000 and around 400 lived in captivity as of the end of 2013, according to data from China's State Forestry Administration.
